Application lcd February 6,1900. Serial No. 4,203. (No model.)

To all whom it may con/cern:

Beit known that I, ISAAC ALLAMAN, a citizen of the United States, residing at Hummelstown, in the county cf Dauphin andState of Pennsylvania, have invented a new and useful Tire-Tightener, of which the following is a specification.

The invention relates to improvements in tire-tighteners.

The object of the present invention is to improve the construction of tire-tighteners and to provide a simple and' inexpensive device adapted to permit a wheel to be readily expanded to tighten the tire to avoid upsetting the latter and capable of effectually preventing the felly-sections from bulging at the joints.

rlhe invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a portion of a wheel provided with a tire-tightener constructed in accordance with this invention, the clip-plate being removed. Fig. 2 is a longitudinal sectional View. Fig. 3 is a' transverse sectional view. Fig. 4 is a sectional view on line 4 4 of Fig. 2. Figs. 5 and 6 are detail views of the overlapping adjustable sections.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

l designates a tire-tightener composed of overlapping adjustable or extensible sections 2 and 3, interposed between the sections 4 of the felly of a Wheel and adapted when the tire 5 becomes loose through any cause whatever to expand the felly sections, and thereby tighten the felly and obviate the necessity of upsetting the same. The sections 2 and 3 of the tire-tightener are provided at their outer ends with parallel grooves or semisockets 6 and?, extending from the tire to the inner periphery of the felly and receiving projecting portions 8 and 9 of the same, whereby the ends of the felly-sections are bound orsupported and are eectually prevented from `sections are rounded to form ribs or protuberances, and the grooves o1l semsockets are approximately semicircular in cross-section to conform to the configuration of the ribs or projecting portions.

The tire may be provided at its edges with ianges 10 to form a groove or channel for the reception of a felly; but when this construc- 6o tion is employed the felly and the sections of the tire-tightener will be provided at their sides with recesses or rabbets to receive the flanges, so that the outer edges of the tire will be flush with the adjacent faces of the felly.

The section 2 is provided with a longitudinal recess 11, formed by sides 12 and receiving a reduced portion 13 oi the section 3, which is recessed at opposite sides at 14 to 7o provide the said reduced portion 13. This construction provides an overlapping substantially telescoping connection,and the sections are adapted to be extended to expand the wheel, and they may also be adj usted inwardly to prevent a wheel from becoming dished should the parts swell in damp weather. The sections of the tire-tightener are extended by means of a ledge or key 15, arranged in the recess 11 and interposed be- 80 tween the back of the same and the adjacent end of the reduced portion 13, and one o1' more wedges or keys may be employed or keys or wedges of different thicknesses may be used to effect the proper adjustment of the felly-sections. The sides of the section 2 fit in the side recesses or cut-away portions 14 of the section 3, and the outer faces of the sections are Hush or in the same plane when the parts are assembled. The reduced portion 9o 13 and the back of the recess 11 are beveled at 16 and 17 to facilitate the introduction of a wedge or key, which is preferably beveled or tapered at the inner end, as shown.

l The tire-tightener is covered by the usual clip-plate or hood 18, provided at itsY ends with perforations for the reception of tirebolts 19 and having a central perforation for a tire-bolt 20, which passes through anlongitudinal slot 21 of the section 3 of the tiretightener. The slot which is formed Vin the reduced portion 13 is of sufficient length to 5 permit the sections to be adjusted 'or ex-V tended to expand a felly to the maximum extent. p

It will-be seen that the tire-tightener is exceedingly simple and inexpensive in construcl Io tion, that it is adapted to be readily operated, and that it is capable of expanding a Wheel and of permitting the lparts to expand without dishing, whereby upsetting the tire and similar operations are obviated.

15 Whatis claimed is-.` Y

1. In a device of the class described, the combination with telly-sections provided at their ends with projections or ribs extending from the tire to their inner periphery, theA zo tire tightener sections provided at their outer ends with grooves .or. semisockets `receiving the projecting portions or ribs of the kfelly-sections, and a Wedge or key for expanding the sections of the tire tightener,

25 substantially as described.

2. In a device of the class described, the combination with a tire, and felly sections,

of the overlapping expansible tire-tightener sections interposed between and interlocked at their outer ends with the felly-seotions, 3o means for expanding the tire-tightener sections, a tire-bolt extending through a longitudinal slot of one of the latter, and a clipplate or hood engaged by the said fastening device, substantially as described. 3 5

3. In a device of the class described, the

combination with a tire andfelly-sections provided with ribs, of the tire-tightener sections 2 and 3 overlapping each other and provided at their outer ends with grooves re- 4o ceiving the projections or ribs of the felly sections, one of the sections of the tiretightenerbeing provided with a longitudinal slot, a key for expanding the sections of the tire-tightener, anda clip-plate orhood having 45 one of its fasteningdevices passing through the said slot, substantially as described. Y

In testimony that I claim the foregoing as` my own I have hereto aiiixed my signature in the presence of two Witnesses.
